Uneven gap between door and jamb

20 yr old front storm door, no brand name anywhere, 2 track, glass on top, screen on bottom in one track fixed and sliding glass panel in second track. The metal frame around the sliding glass panel has given out at the top 2 corners where the spring loaded lever slides into the 2nd door tract to secure the panel into the storm door. I can't afford a new door now, so I'm hoping to fix the metal frame. Advice please. Could a glass shop reconnect the aluminum frame back together? What to do. Thanks.

Our master bedroom previously had a bare wood floor but we decided on carpeting. The closet doors are sliding doors, the kind where there's a metal track along the top of the opening and two doors are hung by rollers on that track. I believe they're called "sliding bypass doors". Anyway, with the bare wood floor there was no problem. To install the carpet we removed the doors and the floor guide (which keeps the doors from swinging in/out). After the carpet was installed I trimmed about 1/2" from the bottom of the doors and rehung them. They slide fine, but I don't know what to do about the floor guide. I got a new floor guide at the hardware store that says it's for use with carpeted floors but honestly I don't know what the process is for installing it. The kit contains the same type of guide that I removed from the wood floor, but also a stack of five or six plastic spacers that, presumably, go below the guide. Looking at it, the only idea I have is to cut a large-ish hole in the carpet where the guide should go, screw the spacers to the floor, then screw the guide to the spacers. Is this right? Do I really have to cut up my new carpet to install this? I considered just screwing the new guide through the carpet and into the floor but the guide bends way too much and the carpet looked very stressed. I'll cut if I have to but before I do I need to know if I'm missing something that's perhaps obvious. Thanks.
